Obata Domain

Overview

Obata Domain (小幡藩, Obata-han) was a feudal domain in Kōzuke Province, in what is now Gunma Prefecture. It was established in 1590, in the eighteenth year of the Tenshō era (天正, Tenshō), during the Azuchi–Momoyama period. Its administrative centre was the jin'ya (陣屋, jin'ya) at Obata — a fortified headquarters, smaller than a castle, from which the domain was governed. The domain lay at the coordinates 36.2284667, 138.9148306, in the area that is now part of the town of Kanra.

History

Obata Domain was founded in 1590, the year in which Toyotomi Hideyoshi completed the unification of Japan and redistributed the country's landholdings among his vassals. The domain's creation falls in the eighteenth year of Tenshō, the era name (年号, nengō) that ran from 1573 to 1592. At that date the Tokugawa shogunate had not yet been established; the domain therefore began its existence under the Azuchi–Momoyama order and continued as a domain of the Edo period that followed.

For part of its history the domain was ruled by the Oda clan, the family of Oda Nobunaga. Nobunaga had been destroyed at Honnō-ji in 1582, and his descendants survived into the Edo period as daimyō; Obata was one of the domains where a branch of that lineage held the lordship.

Territory and Influence

Obata Domain was located in Kōzuke Province, a landlocked province of the Kantō region corresponding to modern Gunma Prefecture. Its capital was the settlement of Obata, where the domain's jin'ya stood. The domain was a small one: its seat was a jin'ya rather than a castle, a distinction that in the Edo period's ranking of domains marked a lord of lesser status than the great castle-holding houses.

The Name in Japanese

The domain's name is written 小幡藩. Its kana reading is おばたはん, and its romaji is Obata-han.

Character by character:

• 小 — read お (o) in this word. Meaning: "small". It is the first element of the place name Obata.
• 幡 — read ばた (bata) here, the second element of the place name. Meaning: "banner" or "pennant", originally a war banner or a flag. The compound 小幡 (おばた, Obata) is a place name; the same two characters also occur as a surname.
• 藩 — read はん (han). Meaning: "domain" — the territory of a daimyō (大名, daimyō, a lord holding land directly under the shogun). The character originally meant a "fence" or "enclosure", and from that came the sense of a bounded, defended territory.

The structure is therefore simple: the place name Obata plus the suffix 藩, "domain". The reading of 藩 as han is the standard one in this compound; the word 藩 appears in the name of every Edo-period domain, so recognising it allows a reader to identify a domain name on sight. Note that the two characters of the place name are read together as a unit — 小幡 is Obata, not ko-bata — which is a common pattern in Japanese place names, where the Chinese-derived readings of the individual characters are replaced by a single native reading.

Legacy

The domain's name survives chiefly in two forms. The first is the place name Obata, still attached to the locality in Kanra, Gunma, where the jin'ya once stood. The second is the association with the Oda clan: Obata is remembered among the domains held by descendants of Oda Nobunaga, a lineage whose history reaches back to the unification wars of the sixteenth century. The domain's foundation in 1590 places it at the very end of the Azuchi–Momoyama period, on the threshold of the Edo period in which the domain system itself was formalised.
